I have been using the official "non-free" Debian packages for installing
the proprietary NVidia modules in some magazine editions of Knoppix,
which are easier to handle than the script-based installation which
contains only precompiled modules for mostly old kernels and library

If I remember corectly, in the last version, installing the nvidia
packages with

sudo aptitude update
sudo aptitude install -t unstable nvidia-kernel-dkms nvidia-glx nvidia-settings

was sufficient to get the proprietary nvidia drivers up and running. It
should work with a flash-installed DVD version of Knoppix, using the
overlay feature.

For "political" reasons, I usually return any hardware that does not run
well with free software to the vendor as a warranty case.

Most graphics chipsets built by Intel (with exception of GMA500) work
well with current versions of xorg/compiz and have low power
consumption. Most ATI/AMD Radeon cards also run well, with a few
exceptions. As a general rule, chances are best to have full
acceleration support with free drivers for cheaper graphics card models,
rather than cards which have computing power and power consumption
several times higher than the rest of the computer and require special
drivers under other operating systems as well.

I would just buy whatever is available in your nearest computer store,
and make sure that you can return it in case it does not work
out-of-the-box under Linux. The vendor has no right to demand you using
a certain operating system in order to get his hardware running, no
matter which is "recommended" on the box.
